Street Pass

Through StreetPass, you can fight, buy from, and recruit the player characters of your friends or strangers. When you get a StreetPass notification, a green character will show up on a random space on the world map. By parleying with this character, you can check the stats of their team, spend gold to recruit the character, or fight. If you win the battle against their team, you have the option of recruiting the player character without paying the gold cost.
